Genesis 21:9-11

Living Bible

⁹ But when Sarah noticed Ishmael—the son of Abraham and the Egyptian girl Hagar—teasing^[a] Isaac, ¹⁰ she turned upon Abraham and demanded, “Get rid of that slave girl and her son. He is not going to share your property with my son. I won’t have it.”

¹¹ This upset Abraham very much, for after all, Ishmael too was his son.
